Alloy 800H can resist corrosion of many corrosive media. Its high nickel content makes it have good stress corrosion cracking resistance under water-based corrosion conditions. The high chromium content makes it have better resistance to pitting corrosion and crevice corrosion cracking. The alloy has good corrosion resistance to nitric acid and organic acids, but has limited corrosion resistance in sulfuric acid and hydrochloric acid. In addition to the possibility of pitting corrosion in halides, it has good corrosion resistance in oxidizing and non-oxidizing salts. It also has good corrosion resistance in water, steam and the mixture of steam, air and carbon dioxide.
